Local administration of IFN-α-iPSC-pMCs alters gene expression profiles in tumor microenvironment.


ABSTRACT: Local administration of IFN-α-producing proliferating myeloid cells (IFN-α-iPSC-pMCs) inhibited the tumor growth not only at the treatment site (right) but also at the distant site (left). We identified genes with log fold expression change ≥ 1 or ≤ −1 in untreated versus IFN-α-iPSC-pMC-treated tumors and iPSC-pMC-treated versus IFN-α-iPSC-pMC-treated tumors for treatment or distant site, respectively. Of the overlapping genes differentially expressed in IFN-α-iPSC-pMC-treated mice, 301/671 distant site and 460/928 treated site genes were ISGs, of which 95.3% and 94.7%, respectively, were type I IFN-related. By gene ontology, the up-regulated ISG signatures were enriched for “T cell-mediated immune responses”, “cytolysis”, and “migration of immune cells” associated genes. Collectively, Local administration of IFN-α-iPSC-pMCs alters the tumor microenvironment and propagates molecular signature associated with type I IFN.
